The hypocrisy of the united states government censoring speech is unbelievable.
Freedom of speech exists so that people can safely say, and talk about controversial things, not so you can talk about the weather.
If parents don't want their kids to hear combinations of sounds that they deem offensive then they should direct their kids to networks / stations that don't make use of them. Networks / stations will decide what and what not to air based on their intended audience and their ratings.
It's not the government's job to decide what people can and can't hear or see just because other people don't want to be exposed to it. In fact, it's the government's job to protect the people who say things people find offensive, that's what free speech is all about
